If you have a 1/3 chance of winning one round and you play 7 rounds. What are the odds you win 4/7 rounds? me and my friends are having a hard time with this question and also i would like to know how you solved it.(adsbygoogle = window.adsbygoogle || []).push({});

Also i'd like to know if a school had 400 kids and there is 365 days in a year. what are the odds of having a persons birthday on each day.

Thanks!
